categorical data

[#1]

I have a categorical dataset and i codded this dataset to numbers. Now I want to know if I feed it to the jmp, i should consider features as nominal or continues, and If I should consider them as nominal, they should be character nominal or number nominal. I will be thankful if you can answer these two questions.

Unless you are doing an ordinal logistic regression, it probably doesn't matter if they are coded as nominal or ordinal. I almost always use nominal.   

Character or numeric coded as nominal are treated the same.

Thank you.

First, welcome to the community.  Unfortunately you have not provided enough information to provide the best advice.  How was the data acquired?  How many categories are there? Are the categories ordered? What type of analysis do you plan to do?  What questions are you trying to answer with the data?  If you could provide the data table or screen shots of what the data looks like, that would be helpful.
